MATLAB: Subplots made by multiple plots

Question

Hi,

I would like to draw a figure consisting of 3 subplots, each made by 4 plots.

Here's my code, to make it more clear…

hold all;
for i=1:4
      subplot(1,3,1);
      plot(S1(:,1,i), S1(:,2,i), c(i));
      xlim([0 1]);
      subplot(1,3,2);
      plot(S2(:,1,i), S2(:,2,i), c(i));
      xlim([0 1]);
      subplot(1,3,3);
      plot(S3(:,1,i), S3(:,2,i), c(i));
      xlim([0 1]);
end
hold off;

My problem is that only the last plots are drawn in the subplots. So I see only one line per subplot, instead of the 4 I intended. Can anyone help me fix this?

Thanks!

Each subplot needs to be held individually.

figure;  hold on
subplot(121)
hold on
plot(1:3)
plot(rand(1,3))
subplot(122)
hold on
plot(4:6)
plot(rand(1,3))
